Choice Black Submersible Hot Water Circulation Pump Solar Brushless Motor800L/H 12V DC 5M

This DC brushless water pump supports two working modes: submersible underwater operation and external dry‐mount installation. Compact‐size, low‐noise running, it is widely used for water heater boosting, equipment cooling, garden irrigation, aquarium water change, fountain, RV, laser machine cooling and other scenarios. It adopts brushless motor for long‐time continuous working, stable water output and long service life.

1. Brushless MotorLow heat generation, long service life, support long‐time continuous operation, stable performance for long‐hour working condition.

2. Dual‐wiring DesignComes with DC female connector & bare wire two connection ways, great compatibility, convenient for different wiring demands.

3. Low Noise & Quiet OperationPlastic pump housing + brushless motor construction, low running noise, will not cause noise disturbance.

4. Compact & Easy InstallationEquipped with fixed mounting base, small footprint, simple installation, support both submersible and external pipeline connection.

1. Submersible (Underwater) ModePlace the whole pump under water. Water flows into pump from water inlet, pump works fully submerged in water.

Note: Ensure the pump body is completely immersed in water for submersible use.

1. External (Dry‐mount) ModePlace pump outside of water tank, connect water inlet to water source via water pipe for water intake.

Note: External installation needs to guarantee sufficient inlet water pressure, avoid idling without water.

✅ Water heater pressure boosting
✅ Industrial equipment / laser cutting machine cooling circulation
✅ Garden irrigation
✅ Aquarium & fish tank water change
✅ Artificial fountain water circulation
✅ Caravan / RV water circulation system
✅ Dishwasher and other small‐equipment water circulation

Warm Tips

1. Voltage Notice: This pump supports DC12V or DC24V only. DO NOT connect to AC household mains directly. Wrong input voltage will burn out the motor and this damage is not covered by after‐sales. Please use matching DC power supply.

2. Forbidden dry‐running: Do NOT let the pump run without water for a long time. Dry‐running will rapidly overheat and damage the brushless motor. Damage caused by dry‐running is not within scope.

3. Two installation modes requirements:

• Submersible mode: The pump body must be fully submerged under water. Keep water inlet away from sediment, dirt or debris to avoid blockage.

• External mode: Need to ensure water can flow into pump inlet smoothly. The pump cannot suck water from too low water level beyond its self‐priming capacity.

1. Parameter explanation: 5m head is the theoretical maximum lift height, actual flow and lift will decrease under real‐world conditions (pipe friction, elbow, water temperature, blockage etc.), actual performance is subject to on‐site working condition, it is not product defect.

2. Wiring note: It has DC female jack and bare wire ends. Please double‐check positive and negative polarity when wiring. Reverse positive‐negative connection will make pump not work and may damage pump.

3. Foreign matter blocking: Please filter the incoming water to avoid sand, debris entering pump inner chamber. Clogging caused by dirt and foreign objects is not quality problem. Regularly clean pump inlet to keep unobstructed.

4. Working environment: Suitable for clean water circulation. Do NOT pump corrosive liquid, oil, slurry or high‐temperature water over 60°C.

5. After‐sales service: If you receive defective or damaged goods, please provide complete unboxing video and clear photos to contact customer service first. Please do not open dispute directly, we will provide you proper solution.
